Nissan Passenger Airbag Lawsuit Connected to Called Nissan class action lawsuit, that alleges that Nissan North America Inc. And Nissan Motor Co. Ltd. Knew about problems with certain Nissan Altima passenger airbag systems and failed to alert drivers. The complaint was filed on September 23, 2026, in the U.S. District Court for the Central District of California. The plaintiffs, on behalf of Class members, allege that sensors attached beneath certain passenger seats of the 2016, 2017 and 2018 Nissan Altima used a malfunctioning front passenger occupant classification system and will both incorrectly determine whether an adult occupant in the front passenger seat is a child or an empty seat, leading to a shutdown of the passenger airbag. The complaint was filed by Alabama residents Kenya Cass, Alisa Steptoe and Cecelia Garcia.

For Nissan Altima owners the class action lawsuit also comes with concerns about warning lights on a vehicle’s dashboard, repair costs, manufacturer notice to consumers, and potential relief from a consumer protection lawsuit. The filing alleges the earlier corrective actions did not address the sensor issues alleged in the vehicles included in the complaint. The Complaint seeks damages and other relief including ordering Nissan to repair, recall, and replace vehicles and extend warranties. The case remains ongoing and no class is certified or settlement reached, as of the information available. It can be useful to look at these issues, in addition to the alleged defect, past recall, and experiences alleged by the plaintiffs, as you consider what alternatives Nissan Altima owners may have in this situation.

1. Nissan Faces a Class Action Lawsuit Over Altima Airbag Sensors

On September 23, 2026, a class action was filed in U.S. District Court for the Central District of California against Nissan North America Inc. And Nissan Motor Co. Ltd., its parent company, identified as Cass et al. v. Nissan North America Inc. Et al., Case No. 5 26-cv-05613. The case has brought concerns over the safety of the passenger airbag to the forefront in regards to the selected Nissan Altima sedans. McCune Law Group released two press statements on October 7, 2026, concerning the case, which was submitted by plaintiffs Kenya Cass, Alisa Steptoe, and Cecelia Garcia. The case was filed on behalf of consumer vehicle buyers and lessees, who purchased or leased the vehicles. It is being alleged that there is a defect in the occupant classification sensors located underneath the front passenger seat that can malfunction, failing to detect an adult passenger. This has led to concerns over vehicle safety, warranty rights, and whether the manufacturer failed to disclose the reported defect to its consumers prior to sale.

Key Details of the Nissan Lawsuit:

• Lawsuit filed on September 23, 2026
• Nissan North America named as defendant
• Parent company also faces allegations
• Three plaintiffs represent affected consumers
• Passenger airbag safety remains central

The issue at hand involves some 2016, 2017, and 2018 Nissan Altima sedans with defective passenger seat sensors that can be incorporated on the same year models. The sensors could confuse your vehicle on whether the seat is empty, occupied with a child, or loaded with an adult while allowing your car to dictate the deployment of the passenger airbags in the event of an accident. According to the lawsuit, sensor failures can lead to a situation where front passengers receive no protection from injury during a crash. The suit also addresses manufacturer disclosures, past recall efforts, and the potential of diagnostic and repair costs to fix the issue.

2. How the Occupant Classification System Is Supposed to Work

As for the Nissan Altima, its front passenger occupant classification system utilizes electronic sensors that are located underneath the passenger seat cushion in order to identify if the occupant is a child, adult, or empty seat. When functioning properly, the system is able to identify the seat as either empty, occupied by an adult, or a child, to determine whether the airbag system is ready to be armed for deployment in the event of a collision. In the complaint, it is stated that the sensors in some Altima models may allegedly fail in one of two ways the sensors identify a seated adult as a child or vehicle occupant sensors identify an occupied seat as empty. This can result in no airbags deploying in a crash, despite the presence of an occupant.

How Sensor Failures Can Affect Safety:

• Sensors sit beneath passenger seat cushions
• System identifies adult and child occupants
• Adults may be misclassified as children
• Occupied seats may register as empty
• Incorrect readings can disable airbags

What the Dashboard Indicator Reveals According to the lawsuit, when the system falsely determines there is no one in a seated position, the PASSENGER AIR BAG OFF indicator fails to light up. This warning light allegedly comes on when the passenger airbag is de-activated and provides a driver with notice of an empty seat. But when the device perceives that an unoccupied seat is filled, the light allegedly doesn’t come on. As a result, the driver and passenger are neither aware that the airbag system is now deactivated. The lawsuit alleges that this “serious safety issue” results in motorists being unaware that an airbag is not currently “armed”, but the lack of a warning doesn’t confirm that all the components of the airbag system are working properly.

3. Nissan’s Recall History Dates Back to 2013

The lawsuit traces the onset of the manufacturer’s occupant classification sensor issues to 2013, asserting that Nissan was aware of the problems before the manufacturer sold the allegedly defective 2016-2018 Altima sedans. Recall 13V-069 was issued by Nissan in February 2013 after the manufacturer found the seat sensors in some 2013 models were manufactured beyond the specifications, and would need to be replaced to ensure they were working properly. In March 2014, recall 14V-138 was issued for certain 2013 and 2014 vehicles after the manufacturer learned the problem could be fixed through software reprogramming. The NHTSA launched an investigation into whether the safety recall resolved the issue in 2015, which was later upgraded to an engineering analysis. Nissan then issued a third recall in 2015 for vehicles that had been incorrectly outfitted with different replacement control units.

Important Milestones in Nissan’s Recall History:

• February 2013 Recall 13V-069
• March 2014 Recall 14V-138
• NHTSA inquiry upgraded during 2015
• Incorrect replacement control units prompted recall
• Earlier repairs remain central allegations

Nissan launched recall 16V-244 in April 2016, affecting almost 3.3 million vehicles. The complaint states that some models received replacement hardware while others did not a decision to simply update the software was made for the Altima. In May 2016, a dealer bulletin was sent to change the logic of a dashboard indicator so that it would appear when the front passenger seat was unoccupied; the complaint alleges that the change confused owners. A second recall was issued in December 2016 because some owners received incorrect control units. That same month, Nissan issued another dealer bulletin providing a hardware retrofit to 2013-2016 Altimas and Muranos that did not correctly resolve the issue in their recall repairs. The complaint claims that Nissan failed to notify owners of this retrofit or provide it as a fix for the 2016-2018 Altimas.

4. Three Nissan Altima Owners Describe Their Experiences

The claim details the experiences of three named plaintiffs who purchased or leased a Nissan Altima they said was affected by the airbag defects. (The other affected owners and lessees are not named as plaintiffs in the complaint.) Kenya Cass was given a used 2017 Altima, which she alleged would give warning lights for the airbag system at random in or about 2025. An auto repair shop told her it would cost about $2,000 to diagnose the problem and about $5,000 to replace a potential airbag. Cass had the sensor repaired and the airbag replaced at an auto repair shop, but the warning light returned. The complaint says this is illustrative of how repairs to diagnose and repair the alleged defect cost owners money and how owners are concerned that the sensor problem has not been fixed after the replacement of the airbag.

Reported Experiences of the Named Plaintiffs:

• Kenya Cass owned a used 2017 Altima
• Diagnosis quoted at approximately $2,000
• Possible airbag replacement cost around $5,000
• Independent repairs did not prevent recurrence
• Warning light returned after repairs

Alisa Steptoe said her 2018 Nissan Altima had recurring sensor-related issues. According to the suit, a Nissan dealer cleared warning lights on her vehicle on two occasions without repairing the sensor hardware itself. The vehicle’s warning lights on each of the dashboard indicators has been on continuously since January 2026. Cecelia Garcia also reported her 2018 Altima incurred a warning light on February 2025 that had been on ever since. All three individuals claim they would not have purchased their Nissan models or would have paid significantly less to do so if the company had disclosed the alleged defect. Those assertions are part of the lawsuit’s claims of issues with vehicle safety and disclosure and financial loss.

5. California Consumer Protection Laws Form the Basis of the Case

The class action currently makes six separate legal claims under California law. One charge involves breach of the implied warranty of merchantability under California Commercial Code; the plaintiffs assert that defective vehicles sold by Nissan were not safe to drive. This count also asserts Nissan breached the Song-Beverly Consumer Warranty Act, which is the state’s primary law governing warranties for consumer vehicles. Another count accuses Nissan of violations of the Consumers Legal Remedies Act, which regulates allegedly unfair or deceptive practices in selling consumer products. As part of this count, the Plaintiffs seek equitable relief and reserve the right to add damages if Nissan does not resolve the alleged defect within 30 days. The count charges additional violations of California’s Unfair Competition Law, which directly proscribes unfair, unlawful, or fraudulent marketing practices and indirectly addresses the root of the problem by forbidding Nissan’s solution.

Key Legal Claims Against Nissan:

• Implied warranty of merchantability breach
• Song-Beverly Consumer Warranty Act violations
• Alleged deceptive consumer sales practices
• Unfair Competition Law violations alleged
• Equitable relief sought under consumer law

The other remaining claims are omission fraud and unjust enrichment. The plaintiffs assert that Nissan knew about the safety defect before consumers purchased or leased the defected vehicles. They also allege that Nissan received financial benefit from the sale of the vehicles with the defective safety sensors. The complaint asks for damages, punitive damages, restitution, attorneys’ fees, and injunctive relief that may include the repair, recall, or replacement of specific vehicles, or the extension of warranties. These are the kind of remedies plaintiffs want the court to consider for the Altima case, but do not imply that any payments, fix programs, or extensions of warranties have been approved or rejected. The outcome of the case will depend on the legal process and whether the plaintiffs and defendants reach any settlement or judgment.

6. Understanding the Nissan Altima and Its Model History

The Nissan Altima is a sedan of similar style produced by Nissan starting in 1992, with the first model produced in June of the same year. The history of the Altima has been with the Nissan Bluebird, which first came out in 1955. Over the years, the Nissan Altima has historically been between the Nissan Sentra and the Nissan Maxima, being smaller, less powerful and less luxurious than the Maxima, and larger than the Sentra. It replaced the Nissan Stanza as the main sedan model in the United States and would go on to become a major part of the Nissan passenger car line. Though the model is considered by the model summary provided here to be a mid-sized vehicle, it can also be considered a compact car.

Essential Nissan Altima Model Details:

• Manufacturer Nissan Motor Company
• Production began during June 1992
• First model year was 1993
• Historically positioned above the Sentra
• Related historically to Nissan Bluebird

The Altima was originally manufactured in the United States for North American markets, and sales were located across the North and South America, Middle East and Australia. For some other markets, the related Nissan Teana was sold between the Altima and Maxima, with those in a few other markets, such as Egypt, only as a few other variations. In 2013, the Teana became a re-badged version of the fifth-generation Altima. Before the Altima, there was the Nissan Leopard, a sedan and hatchback for the Japanese markets, and the popular Nissan Laurel hardtop coupé, which was sold until 2002; the name “Altima” is not a sequel to that name. The Altima was produced at Nissan’s Smyrna, Tennessee plant until June 2004 and the Canton, Mississippi plant had also begun production of the model in June 2004 to make up for the shortage caused by the resignation of the previous plant manager. The lawsuit is not about all the vehicle models years; it’s about certain passenger airbag sensor allegations in a few selected years from 2016 to 2018 of the Altima.

7. Fraud by Omission and Nissan’s Alleged Failure to Disclose

With respect to the fraud-by-omission claims in the complaint, the focus is on the passenger airbag sensor defect. This is where the SUV and sedan crossover became an issue, as the claims focused on whether Nissan knew of the passenger side sensor issue before consumers purchased or leased those vehicles. The complaint emphasizes that consumers have a right to know if there is a potential safety defect with any SUV or sedan before they buy it and that new owners of the Altima vehicle should have known whether the sensor defect was a safety issue that may have prevented the passenger side airbag from deploying in a collision. Additionally, Nissan’s prior recall history and maintenance history are relevant to what the manufacturer knew about failure of the occupant classification system.

Main Allegations Concerning Consumer Disclosure:

• Alleged failure to disclose sensor defects
• Passenger safety concerns before vehicle purchases
• Previous recalls form part of allegations
• Unjust enrichment claim against Nissan
• Consumers seek financial and safety remedies

The plaintiffs request compensatory damages, punitive damages, restitution, attorneys’ fees, and damages and other court orders forcing Nissan to repair, recall, or replace the vehicles in question and make warranties on their performance for the benefit of the owners of the vehicles. The complaints in this case have not been established as proven misconduct on the part of Nissan, and the remedies requested are subject to the procedures of the legal process. Ultimately, this case will be up to a judge to determine whether the cars had this alleged defect, whether the manufacturer was aware of the defect, whether previous corrective measures were adequate, and whether this information was made available to consumers. When dealing with the impact of this lawsuit for affected drivers, the difference between allegation and proven violation of the law can make quite a difference.

8. Vehicle Maintenance, Warning Lights, and Repair Records

Regular servicing can bring attention to a fault with an airbag sensor, electrical issue or dashboard warning light needing expert diagnosis. Routine visits should involve such services as oil and filter changes, tyre rotations, brake checks, battery testing, fluid top-ups and wheel alignments. The mechanic can also look at warning lights, starting problems, electrical faults and erratic behaviour. While none of this will necessarily raise concerns about a passenger airbag sensor fault, attentiveness to warning signs and not ignoring warning lights will go some way to enabling the owner to respond to a potential problem before it is too late. If the passenger airbag light indicates a fault, the driver should not just wait for the warning light to turn off but instead, seek an inspection by an experienced auto technician.

Practical Vehicle Maintenance Reminders:

• Monitor dashboard warning lights carefully
• Schedule regular diagnostic inspections when needed
• Keep dealership invoices and repair estimates
• Record sensor-related repairs and assessments
• Seek qualified help for airbag warnings

Dealers can check to see if a warranty or recall applies, in case a customer notifies an Altima service advisor of a malfunction. Nissan recommends owners to store and retain written documentation such as diagnostic reports and repair estimates, dealer invoices, and previous repairs or services, especially if the same warning reappears after a repair, to document past repairs and repairs made to the vehicle so dealers have documentation of known issues and repairs should a subsequent recall update or legal resolution have any applicability. Nissan dealerships also offer regular maintenance and diagnostic services for other vehicles such as the Murano, Armada, Frontier, and the electric LEAF. For customers of the Altima with concerns about the lawsuit, keeping good records and using a mechanic will help document the condition of the vehicle as the legal case goes forward.

9. Who May Qualify for the Proposed Nissan Altima Class Action?

The proposed class action sets forth specific criteria for conditions under which individuals or businesses who purchased or leased certain Nissan Altima sedans sold in California are eligible to join. The proposed class includes those who purchased or leased a 2017 or 2018 Altima, or a 2016 Altima built after April 1, 2016. McCune Law Group’s larger investigation of potentially affected Altima owners in California and elsewhere includes owners in Colorado, Florida, Illinois, Massachusetts, Michigan, North Carolina, New York, New Jersey, Pennsylvania, Texas, and Washington. Requirements specify that, to qualify, the consumer must have purchased a new or certified pre-owned Altima, leased it with more than 24 months remaining, and still owns the vehicle. Additional criteria concerning accident history, title history, sensor modifications, and evidence of the defect, also need to be met to be eligible to join this case.

Important Proposed Eligibility Requirements:

• Specified 2016-2018 Altima models only
• California purchase or lease requirements apply
• New or certified pre-owned purchases
• Vehicle ownership must still continue
• Sensor failure evidence may be required

Other requirements include that the candidate vehicle has not had the airbags deployed during a crash, has not had a salvage title, and has not had its sensor hardware altered. The vehicle must also have been diagnosed by a dealership as having a sensor failure, or having an airbag light that stays ON when a person is sitting in the front passenger seat. These criteria are aimed at helping the firm narrow down on the vehicles that meet the allegations in the complaint. Drivers should therefore keep any dealership diagnosis, diagnostic results, and bills that document their experiences. As this case is still in an early phase, anyone considering making such a claim should verify his or her individual case with McCune Law Group or an expert on the topic.

10. Current Lawsuit Status and What Nissan Altima Owners Should Know

The class action against Nissan North America and Nissan Motor Co. Ltd. Has been filed in federal court. The case has not yet been resolved. Based on the info you have been provided, no class has been certified, and no settlement or claim money is presently available. McCune Law Group offers free initial case evaluations that are free on a contingency basis (don’t pay unless you get paid through the arrangement set forth) but these details are important for owners who may wish to ask about the allegations. 1) Filing a class action lawsuit does not mean that Nissan is proven to be in the right, or that owners are automatically entitled to recovery. How the case proceeds will determine if the proposed class moves forward and if any repair, warranty or payment remedies are available.

What Owners Need to Know Right Now:

• Federal lawsuit has been filed
• Proposed class remains uncertified currently
• No settlement or claim money available
• Initial case evaluations are offered free
• Repairs and warranties remain unresolved requests

Altima passenger seats will trigger an airbag indicator and sensor if the devices are faulty or defective, and owners are advised to ensure that they have the vehicle checked by an auto professional and retain documentation of the work completed on the vehicle. Consumers interested in purchasing a new or used Altima may also want to compare all models for passenger space, cargo room, vehicle financing, leasing, payment plans, trade-in values, warranties, and coverage options. The information also points out auto dealerships providing extended powertrain warranties, including a rusted wallace warranty of up to eight years or 200,000 miles of coverage, which should not be relied upon as covering the alleged airbag defect. As this lawsuit continues, drivers affected by airbag issues should follow the case and retain appropriate documentation and assistance for airbag safety concerns.
